The difference that will be most noticeable is that a 64-bit application has 4GB of memory to work with, up from 2 on a 32-bit application. You will see fewer crashes due to OUT OF MEMORY errors that occur due to the application not releasing memory when it should and hitting the 2GB limit.A 32-bit OS can't see more than 4GB of RAM; a 64-bit version of Windows has a much higher memory ceiling depending on what OS you have. (Windows 7's ceilings are measured in the hundreds or thousands of gigabytes).With applications ever more hungry for resources (disk space, processor power, graphics rendering power, and memory, 32-bit apps and operating systems are increasingly going away. Within five years, I think seeing an application ship only as a 32-bit app will be considered strange, and installers will install 64-bit applications if they detect a compatible system.
